Roche share price hasn’t exceeded the 20% return since the first swine flu symptoms were reported in Mexico in April 2009, a clear indication that Tamiflu is not the solution to the swine flu pandemic. Relenza, produced by GlaxoSmithKline, is also reporting the same ineffective results primarily over children under 12.

The 500% plus increase of Novavax share price since the swine flu symptoms invaded the media, puts this company at the peak of the high-yielding list of stocks to watch, but also, at the highest risk. For how much longer will Novavax Pharmaceuticals be able to sustain the share price?
